#ABC057B. Checkpoints
Checkpoints
Problem Statement
There are students and checkpoints on the -plane.
The coordinates of the -th student is , and the coordinates of the checkpoint numbered is .
When the teacher gives a signal, each student has to go to the nearest checkpoint measured in Manhattan distance.
The Manhattan distance between two points and is .
Here, denotes the absolute value of .
If there are multiple nearest checkpoints for a student, he/she will select the checkpoint with the smallest index.
Which checkpoint will each student go to?
Constraints
- All input values are integers.
Input
The input is given from Standard Input in the following format:
N M a1 b1 : aN bN c1 d1 : cM dM
Output
Print lines.
The -th line should contain the index of the checkpoint for the -th student to go.

The Manhattan distance between the first student and each checkpoint is:
For checkpoint
For checkpoint
The nearest checkpoint is checkpoint . Thus, the first line in the output should contain .
The Manhattan distance between the second student and each checkpoint is:
For checkpoint
For checkpoint
When there are multiple nearest checkpoints, the student will go to the checkpoint with the smallest index. Thus, the second line in the output should contain .
